| 摘 要： | 烃类微渗漏的间接证据,包括一系列地球物理、地球化学、岩石矿物和地貌异常以及以后认识到的在土壤化学与植物生理方面引起的变异。所有这些现象均与烃类微渗漏密切相关。根据这种地表“蚀变体”的波谱特征,可利用遥感技术在特定波段内将其信息直接提取出来。

| Abstract: | It has been for years in applying hydrocarbon's micro-seepage to prospecting for oil and gas. There are a lot of indirect evidence which are pertinent to hydrocarbon's microrseepage including anomalies of geomorphology, geochemistry and mineral, and recently known abno-mals of soil chemistry, and vegetation physiology. As a matter of fact, these alteration haloes can be divided into following classes: redbeds bleaching haloes, clay enrichment haloes, car-bonatite enrichment haloes, radiation haloes, heat anomaly haloes, geobotanical anomaly haloes, magnetic anomaly haloes, and haze haloes.All of these haloes might exist in overlain beds of reservior in different scales and types. These phenomena can be used as direct and/or indirect indexes to detect oil and gas information with remote sensing means.According to spectral survey on these alteration haloes, it is shown that every one has its own spectral features obviously in the visible, near-IR, and thermal-IR wavebands. So it is available to look for oil and igas with remote sensing means directly. Finaly, our aim is to select the best wavebands for oil and gas. |
